L. williamsii is self-fertile, everything else not. WOW, Ian, I didn't know that! That's the key then to my Lophos, if they bear seeds (and they do) then they are williamsii.

I had to go through them all taking pics of each label to try to recover any lost names, but some were too far gone (about 30 of 250). One of these I mislabeled tho...
